Lesson10: Sludge Digestion and Solids Handling

Introduction. Treatment of sewage sludge may include a combination of thickening, digestion, and dewatering processes. Thickening is usually the first step in sludge treatment because it is impractical to handle thin sludge, a slurry of solids suspended in water. Thickening is usually accomplished in a tank called a gravity thickener.
